What are Anorexiants
Anorexiants are drugs that act on the brain to suppress appetite. They have a stimulant effect on the hypothalamic and limbic regions, which control satiety. Anorexiants are used as therapy for obesity.

What is orlistat?Orlistat blocks some of the fat that you eat, keeping it from being absorbed by your body.

Orlistat is used to aid in weight loss, or to help reduce the risk of regaining weight already lost. This medicine must be used together with a reduced-calorie diet. Orlistat is for use only in adults.

Xenical is the prescription-strength form of orlistat. The alli brand is available without a prescription.

Ok gluconamin, (apitite decreaser) orastat (fat blocker) and green tea (fat burner) all 3 are proven to work at least somewhat and used together thats as good as you can get currently
Looks like you can get carb/sugar blockers too

Dude, I have read and saw so many stuff on the internet and news of how harmful any kinda pills/drugs that promise to get you fit/skinny. They can even cause death, or some other fucked up diseases you will be stuck with for the rest of your life. Spend the time you spend on searching for some magic pills on working out instead, or make peace with your fatness and marry it.
